statHardbound. This volume of the Handbook is concerned particularly with the frequency side, or spectrum, approach to time series analysis. This approach involves essential use of sinusoids and bands of (angular) frequency, with Fourier transforms playing an important role. A principal activity is thinking of systems, their inputs, outputs, and behavior in sinusoidal terms.
In many cases, the frequency side approach turns out to be simpler with respect to computational, mathematical, and statistical aspects. In the frequency approach, an assumption of stationarity is commonly made. However, the essential roles played by the techniques of complex demodulation and seasonal adjustment show that stationarity is far from being a necessary condition. Assumptions of Gaussianity and linearity are also commonly made and yet, as a variety of the papers illustrate, these assumptions are not necessary.

Statistics For Dummies

For Dummies | 1 edition (August 25, 2003) | English | ISBN-10: 0764554239 | 384 Pages | PDF | 3.4 MB

In the numbers explosion all around us in our modern-day dealings, the buzzword is data, as in, “Do you have any data to support your claim?” “The data supported the original hypothesis that . . .” and “The data bear this out. . . .” But the field of statistics is not just about data. Statistics is the entire process involved in gathering evidence to answer questions about the world, in cases where that evidence happens to be numerical data.

Statistics For Dummies is for everyone who wants to sort through and evaluate the incredible amount of statistical information that comes to them on a daily basis. (You know the stuff: charts, graphs, tables, as well as headlines that talk about the results of the latest poll, survey, experiment, or other scientific study.) This book arms you with the ability to decipher and make important decisions about statistical results, being ever aware of the ways in which people can mislead you with statistics. Get the inside scoop on number-crunching nuances, plus insight into how you can
# Determine the odds
# Calculate a standard score
# Find the margin of error
# Recognize the impact of polls
# Establish criteria for a good survey
# Make informed decisions about experiments

This down-to-earth reference is chock-full of real examples from real sources that are relevant to your everyday life: from the latest medical breakthroughs, crime studies, and population trends to surveys on Internet dating, cell phone use, and the worst cars of the millennium. Statistics For Dummies departs from traditional statistics texts, references, supplement books, and study guides in the following ways:
# Practical and intuitive explanations of statistical concepts, ideas, techniques, formulas, and calculations.
# Clear and concise step-by-step procedures that intuitively explain how to work through statistics problems.
# Upfront and honest answers to your questions like, “What does this really mean?” and “When and how I will ever use this?”

Chances are, Statistics For Dummies will be your No. 1 resource for discovering how numerical data figures into your corner of the universe.

Publication Date: 2001-05-29
ISBN-10 / ASIN: 0335208908
ISBN-13 / EAN: 9780335208906
Binding: Spiral-bound

Product Description:

\"An excellent introduction to using SPSS for data analysis...extremely useful for undergraduate students, and covers a good range of material often not found in competing texts. It provides a self-contained resource itself, with more than simply (detailed and clear) step-by-step descriptions of statistical procedures in SPSS. There is also a wealth of tips and advice, and for each statistical technique a brief, but consistently reliable, explanation is provided.\" - George Dunbar, University of Warwick

\"This book is an excellent addition to the research methods literature. It presents the research process, research strategy and SPSS techniques in manageable steps offering clear advice, useful tips and discussion of relevant issues such as assumptions and effect size...this text is written in an encouraging and supportive style. I believe students will read and learn with this book.\" - David Cairns, Macquarie University, Australia

The SPSS Survival Manual throws a lifeline to students and researchers grappling with SPSS. Written in a friendly, jargon-free style, it demystifies statistics and data analysis by guiding you through the entire research process and helping you to choose the right statistical technique for your project. From the formulation of research questions, to the design of the study and analysis of data, to reporting the results, Julie Pallant discusses basic and advanced statistical techniques. She outlines each technique clearly, with step-by-step procedures for performing the analysis, a detailed guide to interpreting SPSS output and an example of how to present the results in a report. The user-friendliness of the manual is enhanced by spiral binding which makes it easy to use at a computer. A recommended reading section points the reader towards additional sources of advice. Illustrated with screen grabs, examples of output and tips, and supported by a website (www.openup.co.uk/spss) with sample data and guidelines on report writing, the SPSS Survival Manual can be used by students and researchers at any level alongside any major statistics textbook.

Doing Statistics With SPSS

Doing Statistics With SPSS



Doing Statistics With SPSS
By Alistair W Kerr, Howard K Hall, Stephen A Kozub

Publisher: Sage Publications Ltd
Number Of Pages: 238
Publication Date: 2002-04-02
ISBN-10 / ASIN: 0761973850
ISBN-13 / EAN: 9780761973850
Binding: Paperback

Product Description:


Doing Statistics With SPSS is derived from the authors\' many years of experience teaching undergraduates data handling using SPSS. It assumes no prior understanding beyond that of basic mathematical operations and is therefore suitable for anyone undertaking an introductory statistics course as part of a science based undergraduate programme. The text will: enable the reader to make informed choices about what statistical tests to employ; what assumptions are made in using a particular test; demonstrate how to execute the analysis using SPSS; and guide the reader in his//her interpretation of its output. Each chapter ends with an exercise and provides detailed instructions on how to run the analysis using SPSS release 10. Learning is further guided by pointing the reader to particular aspects of the SPSS output and by having the reader engage with specified items of information from the SPSS results.

This text is more complete than the alternatives that usually fall into one of two camps. They either provide an explanation of the concepts but no instructions on how to execute the analysis with SPSS, or they are a manual which instructs the reader on how to drive the software but with minimal explanation of what it all means. This book offers the best elements of both in a style that is economical and accessible.
